ELEVATOR FOR BARRELS, aw.

SPECIFICATION forming part of Letters Patent No. 231,793, dated August 31, 1880.

Application filed April 12,1880. (No model.)

To all whom it may concern Be it known that I, LA'LHAM WILEY GREEN- LEAF, of Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Improvement in Elevators for Barrels and other Articles, of which the following is aspecification.

Figure 1, Sheet 1, is a rear elevation of the improvement. Fig. 2, Sheet 1, is a sectional side elevation taken through the line 00 m, Fig. 1. Fig. 3, Sheet 2, is a plan view. Fig. 4, Sheet 2, is a sectional plan view taken through the line y y, Fig. 2;

Similar letters of reference indicate corresponding parts.

The object of this invention is to improve the construction of the elevators for which Letters Patent No. 220,137 were granted to me September 30, 1879, in such a manner as to better adapt them for use in elevating and lowering barrels and other articles from one floor to another in store-houses, warehouses, and other places, and which shall be so constructed as to load and unload themselves while in motion.

The invention consists in constructing an elevator with stationary skids and stops at the lower floor for placing the load upon and removing it from the carrier, and also in constructing an elevator with stationary skids, pivoted eXtei'ision-skids, pivoted stops, shafts, crank-arms, connecting-bars, and a lever at the upper floor for placing the load upon the carrierin its upward movement and removing the load from the carrier in its downward movement, or allowing the loaded carrier to pass freely, as will be hereinafter fully described. a

A represents a lower floor, and B an upper floor, ofa store-house or otherbuilding, through which floors the well-hole of the elevator is formed.

To the floor-timbers of the floors A B, at the opposite sides of the well-hole, are attached posts 0. To the posts 0, a little above the lowest floor, A, are attached bearings D, in which revolve the journals of the shaft E. The bearings D are slot-ted toreceive the fastening-bolts F, so that the said bearings D can be moved up or down to regulate the tension of the endless chains, hereinafter described.

To the shaft F, at the inner sides of the posts 0, are attached wheels G, the faces of which are so formed as to engage with the links of the chains H, which pass around them, and thus prevent the said chains from slipping upon the said wheels. The chains H also pass around similar chain-wheels I, the journals of which revolve in hearings in standards, posts, or. frames J, attached to the upper floor, B.

K is a bar which is bent four times at right angles, giving it a crank form, as shown in Figs. 1 and 2. The ends of the bar K are rounded off and work in lugs attached to or formed upon links of the chains H, and upon the middle part of the said bar Kare formed,

or to it are attached, the middle parts of forked I or semicircular bars or arms L, to receive the barrel or other article to be carried. WVith this construction the weight of theswinging bar K keeps it in a vertical position as it is carried bythe endless chains 11.

To the upper floor, B, at the rear side of the well-hole, are attached upwardly-projectin g bars M, to prevent the bar K, as it passes over the upper chain-wheels, I, from swinging out so far as to strike the said floor B.

.To one end of the shaft E is attached a gearwheel, N, the teeth of which mesh into the teeth of a small gear-wheel, O, pivoted to the upper part of the bearings D.

To the outer journal of the gearwheel O is attached the crank P or pulley, by which 1110- tion'is given to the elevator by hand, or by any convenient power.

To the floor A, at the front and rear sides of the well-hole, are attached inclined skids Q, for convenience in rolling barrels to and from the elevator.

To a cross-bar, R, attached to or formed upon the upper parts of the bearings D, are attached the upper ends of the front and rear stops, S T, the lower ends of which are curved inward and are attached to each other.

To the middle parts of the stops S '1 are attached the ends of a bar or plate, U, through a hole in the center of which the shaft E passes to strengthen the stops S T and prevent them from swinging.

The forward stop, S,is concaved or bent inward, to allow the barrel, when rolled up the skids Q against the stop S, to be in such a position as to be taken up by the carrier K L of the elevator as the said carrierpasses up from the lower chain-wheels, H.

The rear stop, T, is bent or inclined outward, so that as the loaded carrier K L descends the barrel cannot pass down between the said stop and the inner ends of the rear skids Q, but will be stopped in such a position that as the carrier K L continues to descend the said barrel will roll down the said skids to the floor.

The well-hole of the lower floor, A, may be made so small that only the unloaded carrier K L can pass through it. The well-hole of the upper floor or floors, B, must be made large enough for the loaded carrier K L to pass up and down freely.

To the upper floor or floors, B, are attached inclined skids V, which, owing to the enlargement of the well-hole and the fact that the loaded carrier must pass them, have to be provided with extension-pieces W. The extensions W are made in U form, or have their free or inner ends connected to keep them in proper relative position. The outer ends of the extensions W are rigidly attached to shafts X, the inner ends of which work in bearings in the skids V.

The outer parts of the shafts X work in bearin gs attached to the floor B, and to their outer ends are attached crank-arms Y, to which are pivoted the outer ends of the con neeting-bars Z.

The inner ends of the connecting-bars Z are brought together and are pivoted to the lever a, the upper end of which projects into such a position that it can be conveniently reached and operated.

The lower end of the lever to is attached to the outer end of a shaft, 1), which works in bear ings in the lower part of the standard, post, or frame J, and in bearin gs 0, attached to the bar d, that crosses the central part of the wellhole.

To the inner part of the shaft I), at the center of the well-hole, are attached stops 0, made in the form of sectors of circles, so that they may be turned down toward either of the extension-skids W, according to the direction in which the elevator is to be run.

In using the elevator, if a barrel is to be raised from the lower floor to the upper floor, the barrel is rolled up the forward skids Q, against the forward stops, S, and the upper end of the lever a is drawn back, so that the barrel will be taken up by the carrier K L, and removed fronlthe said carrier by the rear extension-skids W and the stops 6.

When a barrel is to be lowered from the upper floor to the lower floor the lever ais pushed forward, and the barrel is rolled up the forward skids V Wagainst the stops 6, so that the barrel will be taken up by the carrier K L, carried over the wheels I, and down at the rear side of'the elevator, and will be removed from the carrier K L by the rear stops, T, and skids Q.

When a barrel is to be moved from an intermediate to a lower floor the levers a of the floors above the said intermediate floor are turned into a vertical position, so that the carrier K L and its load can pass up and down through the said floors freely.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In an elevator, the combination of the stationary inclined skids Q Q and the stationary stops S T, substantially as herein shown and described, whereby the load is placed upon the carrier KL in its upward movement and removed from the said carrier in its downward movement, as set forth.
